摘要： Systems and methods for downlink transmission using a wideband unlicensed band carrier in 5G networks are described. The gNB determines, based on LBT, which LBT subchannel(s) in a BWP are available during a COT. The gNB transmits an indication of the available subchannels in DCI format 2_0 of a GC-PDCCH of one of the available subchannels and subsequently transmits a PDSCH using the available subchannel(s). The gNB may configure multiple opportunities during the COT and transmit the GC-PDCCH after the initial opportunity. The PDSCH is transmitted on all available subchannels during the COT and, during an initial portion of the COT, may transmit the PDSCH by puncturing symbols of the unavailable subchannels. The indication may include a bitmap of available subchannels or if the LBT outcome is not available, may indicate all or none of the subchannels or available or that the outcome is not available.

摘要： Systems and methods for interlace PUCCH transmission in 5G networks are described. The gNB sends an RRC message to a UE. The RRC message provides one or more PUCCH interlace allocations within a BW. Each PUCCH interlace allocation has a PUCCH format for each PUCCH interlace. Each PUCCH format contains a different PUCCH interlace index. The UE sends a PUCCH interlace in the BWP based on the PUCCH interlace allocation. A PUCCH in the allocated PUCCH interlace has a cyclic shift that is dependent on a resource block number in the allocated PUCCH interlace within the BWP.

摘要： Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. A channel state information (CSI) report may include a CSI part 1 transmission and may be configurable to include a CSI part 2 transmission. The UE may determine a first number of coded modulation symbols per layer to be used for the CSI part 1 transmission on a physical uplink shared channel (PUSCH) without uplink shared channel (UL-SCH) data. The first number of coded modulation symbols per layer may be determined as: a minimum of a first term and a second term if the CSI report includes the CSI part 2 transmission; and the second term if the CSI report does not include the CSI part 2 transmission.
